We describe an interactive, computer-assisted framework for com-
bining parts of a set of photographs into a single composite picture,
a process we call "digital photomontage." Our framework makes
use of two techniques primarily: graph-cut optimization, to choose
good seams within the constituent images so that they can be com-
bined as seamlessly as possible; and gradient-domain fusion, a pro-
cess based on Poisson equations, to further reduce any remaining
visible artifacts in the composite. Also central to the framework is
a suite of interactive tools that allow the user to specify a variety
of high-level image objectives, either globally across the image, or
locally through a painting-style interface. Image objectives are ap-
plied independently at each pixel location and generally involve a
function of the pixel values (such as "maximum contrast") drawn
from that same location in the set of source images. Typically, a
